話題13健康(Health),本文主要講述人們的飲食習慣在改變,大家轉(zhuǎn)而追求自然健康的飲食。自然的食物包括蔬菜、水果和谷物。他們種在地里并且是有機食物。自然的食物還包括能讓家禽自由活動的牧場。人們對糖的理解也不一樣,實際上,糖對人體并無益處。,美文研讀,1.A在第一段“becausemuchofthefoodtheyeat,especiallyprocessedfood,isnotgoodforthehealth”可知加工過的食物人們并不感興趣。因此該選項錯誤,故選A。其他選項是正確的:選項B,由在第二段“Thisinitselfisanaturalprocesscomparedwiththeuseofchemicalsandfertilizers,themainpurposeofwhichistoincreasetheamount—butnotthequality—offoods”可知,化學肥料到處都被使用,因為要提高產(chǎn)量而不是質(zhì)量。選項C,由第二段中的“Naturalfoods,forexample,arevegetables,fruitandgrainwhichhavebeengrowninsoilthatisrichinorganicmatter”可知,農(nóng)民使用有機肥料種自然健康食物。選項D,在第三段“Chickenskeptinthiswayarenotonlytastelessasfood;theyalsoproduceeggswhichlackimportantvitamins”,雖然沒有直接說明,但是可以知道沒有自由行走的雞生的蛋無重要的維生素。,2.C從第三段可知雞是在農(nóng)場活動。A是森林,B山川,C草地,D公園,所以答案是C。3.A通讀全文提到自然健康食物和少吃糖可知選A。4.sugarisunnecessaryfood,butweeatittoomuch.Soweshouldeatlesssugar,[復記強化]pare3.amount4.feed5.attention6.expert7.意識到8.“越來越濃的興趣”或“越來越感興趣”9.被……影響到10.主要的目的11.擁擠地住在一起12.不需要的食物,一、句子翻譯1.strength/advantages,plentyof/lotsof,bine,abalancedmenu3.Accordingto,neither,nor4.Inordertokeepfit/healthy,weoughttoknowmoreaboutourbody.,知識運用,5.Don’teatfoodthatcontainsmuchsugarandfat.6.Itisbettertoeatfreshfruitsandvegetablebecausetheyhavemuchfibreandvitamins.7.Youshoulddoregularexercisetobuildupyourbody.8.Inaword/all,healthyfoodandgoodlivingconditionaregoodwaystokeephealthy.,二、短文填空①loseweight②doesharmto③Asweknow④areaddictedto⑤insteadof⑥communicatingwith⑦leadto⑧formgoodeatinghabits⑨payattentionto,本篇為疾病介紹類說明文,向讀者描述了瘧疾的癥狀、人類所受的危害及此疾病傳播的原因。1.A細節(jié)理解題。由文章第一段第四句中的earninglessthantwohundreddollarsayear可推斷這些家庭是貧困的,故A正確。根據(jù)句中“notunusual”可排除B項。第一段最后一句“nofamily,village,hospital,orworkplacecanremainunaffectedforlong.”可知C項錯誤。D項屬于事實,而非原因。,典型例題,2.B推理判斷題。由最后一段的第三句(buttheyhavebeeninshortsupplyandareveryexpensive)得知B項正確。根據(jù)最后一段第一句“Fordecades,thefirst-choicetreatmentformalariaparasitesinAfricahasbeenchloroquine,achemicalwhichisverycheapandeasytomake.”可知是有治療藥物的,排除A。由“Malaria,theworld’smostwidespreadparasitic(寄生蟲引起的)disease”可知“malaria”是由“parasites”所引起的,所以不需要“resist”,排除C?!癐fthesedrugsshouldfail,nobodyknowswhatwouldcomenext.”可知D項有誤。,3.D細節(jié)理解題。由文章第二段倒數(shù)第三句話(itsabilitytochangerapidlytodefenditselfandresistnewdrugshasmadeitnearlyimpossibletocontrol)得知D項正確。由“Someofthedisease’sspreadisduetoglobalwarming”可知A項與文意相反。由第二段倒數(shù)第二句“Studiesshowthatmosquitoesarepassingonthevirusmorefrequently,andtherearemoreoutbreaksincitieswithlargepopulations”可知B、C項有誤,B項中“its”指代“mosquitoes”而非“thedisease”,C項為結(jié)果而非原因。,4.C細節(jié)理解題。由文章第二段第三句“Malariaparasiteslivebyeatingtheredbloodcellstheyinfect”可知C項正確。A項理解有誤。根據(jù)文中第二段第五句“Ifitdoesn’tkillyou,malariacanhappenagainandagainforyears”可排除B項。而第三段第一句“Malariastartssuddenly,withviolentchills,whicharesoonfollowedbyanintensefeverand,often,headaches”可知D項有誤。5.D主旨大意題。根據(jù)全文所討論的內(nèi)容得知,選項A,C在第二段討論到了,選項B在第一段討論到了。,[復記強化]disease2.seek3.earn4.income5.remain6.defend7.控制8.經(jīng)常地9.爆發(fā)10.十年11.有抵抗力的12.可用的13.使…相關(guān);使……依14.傳給……,文章說明了空氣質(zhì)量與人們心臟健康之間的關(guān)系。1.A主旨大意題。本文的主題句是第一段最后一句Butthereisanotherfactorthatcancauseyourheartproblemsmoreimmediately:theairyoubreathe可知。注意,but,however等是作者表達自己觀點的重要提示詞,即常常是主題句的信號詞。,實戰(zhàn)演練,2.C詞義猜測題。根據(jù)這句話中的信息詞small及and可知,與small并列的或“同現(xiàn)”的應是low,故選relativelylow。3.C是否判斷題。由NOTtrue可知,選項是三正一誤,題目要求考生選出錯誤選項。選項C與第二段最后一句意思相反,錯誤,故選C。選項A與第二段第一句but后的內(nèi)容相同,正確;由第三段第一句可知,選項B正確;由文章最后一句可推斷出,應當對污染物制訂更加嚴格的規(guī)定,選項D正確。,4.A寫作目的題。本文主要說明一個事實和現(xiàn)象,給人們提供相關(guān)知識和信息(inform),而不是“說服”“描寫”“娛樂”。5.A文體推斷題。據(jù)文章內(nèi)容判斷,本文應選自asciencemagazine,而不是選自“科幻小說”“旅游指南”“個人日記”。,[復記強化]fatty2.risk3.breathe4.pollution5.quality6.強調(diào)7.血壓8.襲擊9.先前的10.因素11.sufferfrom12.beawareof13.不顧,不管,第一步,寫出關(guān)鍵詞。publicplaces2.acrossthewholecountry/alloverthecountry3.bansmoking4.carryout5.aim6.Indoor7.takemeasures8.post9.signsofsmokingban10.affect,典型例題,二、信息表達。1.TheChinesegovernmenthasdecidedtobansmoking.2.TheChinesegovernmentwillcarryoutthesmokingbanacrossthewholecountryfromJanuary1,2011.3.Theaimofsmokingbanisthattherewillbenosmokinginallindoorpublicplaces.4.Weshouldtakesomemeasuressuchaspostingsignsofsmokingban.,5.InChina,thereareabout350millionsmokers.6.75%ofthesmokersaremen.7.25%ofthesmokersarewomen.8.About540millionpeopleareaffectedbysecond-handsmoke.9.100thousandpeoplediefromsecond-handsmokeeveryyear.,第三步,信息整合。第一組:TheChinesegovernmenthasdecidedtobansmokingandwillcarryoutthesmokingbanacrossthewholecountryfromJanuary1,2011,theaimofwhichisthattherewillbenosmokinginallindoorpublicplaces.第三組:InChina,thereareabout350millionsmokers,amongwhom75%aremenand25%arewomen.,第四組:About540millionpeopleareaffectedbysecond-handsmoke,whichcauses100thousanddeathseveryyear.第四步,連句成篇。Torealizetheaim,What’sworse,Therefore,itisnecessaryforthegovernmenttobansmokinginourcountry.,TheChinesegovernmenthasdecidedtobansmokingandthebanwillbecarriedoutacrossthewholecountryfromJanuary1,2011,theaimofwhichistomakesurethattherewillbenosmokinginallindoorpublicplaces.,第五步,潤色提升。該作文各個句子依次使用的語法句式有:定語從句、非謂語和虛擬語氣、并列句(while),被動語態(tài)、固定表達(銜接性句式what’sworse)和簡單句。為了進一步豐富作文的表達,可以使用的語法句式還有:感嘆句、強調(diào)句、
